The 1620 Road Fire is now 75 percent contained with 50 percent control.  Oregon Department of Forestry spokesperson Christie Shaw says firefighters were able to take advantage of increased humidity and wetting rain Wednesday to focus on line construction.  Firefighters are continuing to construct and secure fireline around the perimeter.  Fire size has been revised to 80 acres.  A Type 3 organization from Central Oregon Fire Management Service is managing the fire.  Resources on the fire include hand crews, fire engines, dozers, and excavators.  A Type 2 helicopter is available as needed.  Specific resources assigned to the fire have been pre-identified to support initial attack within the area if there are any new fire starts.
